tions, of whichthe following is a specification.

The present invention has reference to certain improvements in foundations for coke ovens and has reference in particular to the construction of said foundations and the arrangement of the fiues for leading off 7 the spent gases. The main object of themvention is to so arrange the fines and passages that the spent gases will be collected uniformly from the entire lower portion of each heating wall and willbo delivered from an entire bench of ovens uniformly to the exhausting fans, stack, or other disposal connection.

Another feature of the invention has refsuch that they may be built up from standardized forms of block with a 'minimum amount of labor and with 1 a minimum wastage of blocks in the construction.

Still another object of the invention is to so construct the foundation and the spent gas take-off tunnels that the central portion of the foundation of the bench may be used for the accommodation of other features of I arrows, the central construction, such as for'the accommodation of preheating regenerators or the like, and without the necessity of materially changing or modifying the essential planning of the foundation itself.

' Other objects and uses of the invention will appear from a detailed description of the same which consists in the features of construction and combinations of parts hereinafter described and claimed.

Referring to the drawings: I Figure 1 shows a vertical longitudinal section-through the and foundation embodying the features of the presentinvention;

Fig; 2 shows an enlarged detail section of. the construction shown in Fig. 1, said section being taken on the line 2-2 of Fig. 1 looking in the direction'of the oven being shown in section and the adjoining ovens in elevation; 'f Fig. 3 shows an enlarged plan detail of one of the sole blocks;

' tion of the arrows walls is the same central portion of an oven Fig. 4 shows'a side elevationof the block shown in Fig. 3; and

Fig. 5 shows a horizon al section taken on the line 5-5 of Fig. 1 looking in the directhe central portion of the foundation being broken a way for the purpose of shortening the figure.

InFig. 2 l have shown the lower portions of three ovens and the foundation beneath them, the ovens being designated 6, 7 and 8, respectively. The oven 7 with its foundation is sectioned on the line 2-2 of Fig. 1. The oven 7 is shown as ha'vihg the heating walls 9 and 10, and for pui oscs of convenience the construction of hese heating as that i lustrated in Letters Patent of the United States No. 1,132,685, which was filed Septer. her 8, 1914, and issued March 23, 1915 and 0. which application this present applicatioi. is a division. The gases from each heatin wall collect in a longitudinal passage 11 beneath said wall, and the gases for each ovdn travel from the passages 11 to a sole passage 12 beneath the oven. The passage 12 is formed by a series of sole blocks 13, the construction of which is shown in detail in Figs l3 aid 4:. Each of these blocks has a longitudinal opening and a transverse opening [which together form a Maltese cross, as is i tell shown in Fig. 3. The longitudinal-openings of the sole blocks go to form the and the transverse openings provide communication between the-passages 11 and the sole passage. It will thus be seen that the sole blocks perform the functionof sustainsole passage 12,

ing the load of the c'arbonizing; chamber and I also'sustain the inner sides (/f the heating walls, as well as providing communication from the passages 11' to the sole passage.

the bench of gases find their way into said tunnel uniformly throughout its length. Underneath the sides of the bench are the tunnels 16 and 17. These collect the spent gases from the various ovens of the bench and carry them to a suitable disposal apparatus, such for example as a fan or stack, or the boilers of a power house The tunnels 16 and 17 are shown as communicating with the cross COHDQCUOA 15 establish coma transverse j 18 whichv leads to the no disposal plant.- The ends of the tunnels 14 connect with the bench tunnels 16 and 17 by means of the downcomersl9 and 20. The

' draft producing'means than others.

It will be seen from an examination of Figs. 1 and 5 that the tunnels l6 and 17 lie close to the sides of the bench and underneath the end portions of the ovens. It will also be observed that the central portions of the ovens are sustained by a longitudinal pier or the like 22 between the tunnels 16 and' 17. By placing the tunnels at the sides of the bench in the manner described, the connections from the tunnels 14' to the tunnels 16 and 17 are shortened u and at the same time a considerable space s .left beneath the central portion of the bench of ovens, unoccupied except by the pier 22 or.. any other suitable appliances or mechanisms which,

may be built into said space. In other words, there is left available a considerable space for the accommodation of other appliances. In my .co-pending application for Letters Patent of the United States on improvements in regenerative coke Ovens, Serial No. 10,041, filed in the United States Patent Oflice February 23, 1915, I have shown an oven construction in which this space is utilized for the accommodation of regenerators for preheating the air when it' is desired to use such an arrangement. It is evident that this space might be used for the accommodation of other constructions than regenerators, if so desired.

While I have herein shown and described only a single construction embodying the features of my invention, still it will be evident that many other constructions might bedevised or adopted without departing from the spirit of the invention.

I claim 1. The combination with a bench of coke ovens having heating walls, of a foundation on which sa d coke ovens are mounted, there being a passage for, spent gases located immediately beneath and extendingthroughout the length of each heating wall for the purpose of collecting spent gases from the entire lower portion of said wall, a sole passage beneath the sole of each oven and extending throughout the length ofthe oven, a plurality of gas connections from the spent gas w passages ofeaehoven to the sole passage of said oven, a transverse tunnel beneath each sole passage and exten ing across the bench,-

. aplurality of connections'from each sole passage to the corresponding transverse tunnel, a spent gas tunnel underneath each side i 'to en adjacent tunnel.

of the bench, and downcomers from theends of the transverse tunnels to connect the same with the spent gas tunnels, whereby there is provided a space beneath the central portions of the ovens of the bench, and beneath the spent gas tunnels thereof.

2. The combination with a bench of coke ovenshavin heating walls, of a foundation whereon said ovens are mounted, said foundation havin ,a' spent gas tunnel extending along each o its side portions and beneath the ends of the ovens, the base portion of each oven being provided with a spent gas passage underneath each of its heating walls and with a sole passage underneath its carbonizing chamber and with a transverse tunnel underneath its sole passage, there being a plurality of cross connections from the spent gas passages of each oven to the sole passage thereof and a plurality of vertical connections from each sole passage to the corresponding transverse tunnel, and there being a downcomer from each end of each transverse tunnel to the adjacent spent gas tunnel.

3. The combination with. a bench of coke ovens having heating walls, of a line of sole blocks beneath the sole of each oven serving pport the carbonizing chamber and the interior portions of the heating walls of said oven, there being a spent as passage at each side'of said line of so e blocks, each sole block being provided with a longitudinal opening and a transverse opening communicating with each other inthe form of a Maltese'cross, the longitudinal openings of the sole blocks together constituting a sole passage and thetransverse openings of said blocks establishing communication from the gas tunnel'in each of its side portions, said tunnels extending throughout the length of the foundation, and the foundation being provided with a plurality of downcomers-located outside of the tunnels, the lower end of each downcomer communicating with the .5. The combination with a bench of coke ovens havingheating walls, of a line of sole blocks beneath the sole of each oven servin to support the carbo'nizing chamber of sai oven, there being a spent gas passage at each side of said line of sole blocks adapted to receive spent gases from the correspondin heating wall, each sole block being provided a bench of coke ovens, said foundation beingprovided with a spent.

' longitudinal openings of the sole blocks together constituting a, sole passage and the transverse openings of said blocks establishing communication from the spent gas. pas- 7 sages to said sole passage, 21 spent gas tunnel underneath each side of the bench of ovens and lying heloyv the end-portions of 10 the ovens, and a downeomer from each end of each transverse tunnel to the adjacent spent gas tunnel.
